Track: Java - Propelling the Ecosystem Forward

Location: Broadway Ballroom South Center, 6th fl.

Day of week: Monday

Java continues to evolve to support an ever-changing ecosystem of applications, languages, and platforms. Whether you are building systems that run at scale, or applications for mobile devices, performance and features are key. This track will focus on how you can build better software, innovate in new spaces, and improve efficiency by leveraging improvements in the JDK.

Track Host:
Haley Tucker
Senior Software Engineer, Playback Features @Netflix

Haley Tucker works on the Playback Features team at Netflix, responsible for ensuring that customers receive the best possible viewing experience every time they click play. Her services fill a key role in enabling Netflix to stream amazing content to 65M+ members on 1000+ devices. Prior to Netflix, Haley spent a few years building near-real-time command and control systems for Raytheon. She then moved into a consulting role where she built custom billing and payment solutions for cloud and telephony service providers by integrating Java applications with Oracle platforms. Haley enjoys applying new technologies to develop robust and maintainable systems and the scale at Netflix has been a unique and exciting challenge. Haley received a BS in Computer Science from Texas A&M University.

Trackhost Interview

QCon: What's the big picture you're looking to accomplish in the Java track this year at QConNY?

Haley: Since we are coming up to a new Java release, I wanted to highlight some the features and improvements that are coming with Java 9 as well as interesting work people are doing with Java 8. What you see in the track is a mix of new features, Java 9 migration stories, and also some of the cool projects that Oracle and the Open Source community are investing in.

QCon: If you had to pick just one, what are you most excited about for QCon NY?

Haley: Probably the Graal talk. When I think about what Thomas is working on, it kind of blows my mind. I'm really interested to hear about how they're achieving language interoperability within the same runtime and what the potential is for this in the real world.

QCon: What do you recommend that a lead developer focus on in the months ahead?

Haley: One area that I'd like to understand more deeply is machine learning. I keep running into problems in my current role which seem like they could benefit from a machine learning approach, so I think there is a lot of value in understanding that space as well as which use cases are a good fit.

Graal Compiler Architect @Oracle

Current language runtimes often execute in isolation -- running in different processes, using different compilation infrastructure, and maintaining their own garbage collectors. There is no reuse of infrastructure and cross-language communication is inefficient. Our vision of the future of execution runtimes is Graal: an integrated, polyglot, high-performance execution environment. Its core is a new just-in-time compiler for the Java Virtual Machine. Graal doesn’t only support Java-based...

Spring Framework Committer @Pivotal

In the past year, Netflix shared a story about upgrading their main gateway serving 83 million users from Servlet-stack Zuul 1 to an async and non-blocking Netty-based Zuul 2. The results were interesting and nuanced with some major benefits as well as some trade-offs.

Can mere mortal web applications make this journey and moreover should they? The best way to explore the answer is through a specific use case. In this talk, we'll take 5 common use cases in web application development...

The modern Java Virtual Machine (JVM) is the culmination of millions of hours of expert engineering, and is the foundation on which enormous portions of the digital landscape are built. However, as a runtime for AWS Lambda functions, the JVM is often derided as being a poor fit for an ephemeral world. The truth of the matter is that the JVM is an excellent choice of runtime for a wide range of AWS Lambda use cases, and developers need not even constrain themselves to just the Java language...

Technology Associate @GoldmanSachs

With each passing version of Java, frameworks must adapt and transform in order to stay current. Eclipse Collections is a collections framework for Java. It has JDK-compatible List, Set and Map implementations with a rich API, as well as additional types not found in the JDK such as Bags, Multimaps and BiMaps. Eclipse Collections also has a full complement of primitive containers.

In this session, we will cover some of the newest features from the 8.0.0 release including the use of...

CSO @Speedment

Migrating a Java 8 application to Java 9 is not just an exercise in API management, but also a learning experience in areas such as memory management and package dependencies.

This talk will share insights from our experience migrating Speedment to Java 9 with a focus on 2 key areas. First, Speedment is an ORM with a Java 8 Streams API and one of its prominent features is acceleration based on in-memory off-heap caching of data. Because it relies on the efficient handling of Strings...
